From what I saw in the pits, roughly 75% of the cars were turbo. Is it cheaper power, more reliable, consistency, or other?

A turbo LS with mild camshaft and stock rocker gear can make 1000hp, same with a gen III hemi. You can make a lot of power with a mild engine. One year on drag week there was a guy who won the sealed hood award and it was a turbo corvette than ran low 8s or high 7s. I don't think you could do that with any other power adder.

That's why there are so many stock block turbo LS's making 1200+ to the wheels. If they were N/A or nitrous motors they wouldn't live. You lose VE with a turbo because of the backpressure increase, but they don't require physical hp to turn like a blower. Prochargers make good power, but are fragile in comparison plus put additional load on the crank, and they are both easier on parts than nitrous. If you are willing to embrace EFI and can fabricate a turbo kit, they're the best power adder out there, especially for drag and drive type events. Many of those cars have bolt on turbo kits available, so you don't even have to do any hard fabrication to do a turbo LS in a Mustang or Camaro.

Turbos are al of the above except "cheaper." Not that they are more expensive- its probably equal between a complete sorted Paxton type and a Roots type when all is said and done. Computer controlled port fuel injection has really made turbos much more feasible than back in the carburetion days. Keep old mopars alive.

I keep going back and forth on turbo stuff, I have a 6.4 Gen III core on the stand I would love to turbo one day. 68 Barracuda Formula S 340

I was looking at a screw supercharger for a project and it was going to be like 5k just for the unit. I can buy 2 decent turbo's, intercooler and wastegates for 4000.00 that will make more power. The down side is looks and sound though, the classic supercharger type of install always looks and sounds better. I became a turbo believer first time I made a home built setup that made 365 rwhp out of 80 cid and basically had no idea what I was doing back then.

Definitely agree with this too. N/a, nitrous or blower cars sound better. A typical junkyard LS turbo setup does not sound aggressive at all. The only other drawback to turbos is they're more difficult to tune, you have more degrees of freedom with it and they're intertwined pretty heavily. Blowers are an easy transition for a nitrous or N/A guy as it's just making sure the fueling is correct and you then manage the power with timing. With a turbo car you have to juggle boost and timing at the same time, as pulling timing typically increases boost. However so many are running them now it's easy to get help, especially if you're running one of the more popular fuel injection setups.

My son & I have been hanging out at a local race shop that builds turbo kits & roll cages, they have a weekly hang out night to bench race & do quick projects that night for the ones hanging out. After checking out various customers projects, seeing the shops no prep 1/8 stuff they race & watching how easy it really is, my daily ‘67 C10 now has a turbo with a terminator X & my son’s FB RX7 now has a turbo with a blow thru Holley 650DP & MSD controlling timing. My truck, I got it together 1 week before RMRW 2.0 2022 & I did the whole week with 0 issues & now have about 25k miles on the set-up with only a O2 that I’ve had to replace. I am planning a turbo for it ‘67 Barracuda & it will be blow thru. The main thing I have seen is using quality parts & planning out the routing, it really makes for a nice driving set-up vs a high compression, big cam NA set-up 1967 Barracuda Formula S 383 1967 Chevy C10 Short Stepper 1980 Macho Power Wagon LWB 318 2021 Toyota Supra

Turbos recover some of the exhaust loss. It's all about overall efficiency. "We live in a time when intelligent people are being silenced so that stupid people won't be offended".
